Anyway, in a day, a petrol bunk attracts not less than 1000 users (approx). Now the apprentice who fills up air would definitely pocket Rs.4000 per day. Even if the entire collection is shared with four or five other apprentices of the bunk his share would be not less than Rs. 800 per day. Cool man! this amount is 100% more than a salary earned by a teacher working in a middle level matriculation school.
In some petrol bunks, 50% of the collection should be handed over to the bunk management. Even then I consider this venture is a lucrative one.
